Radio Band Expanders

The Radio Band Expander (also known as a Wave Expander or FM Frequency Expander) enables the original equipment radio in Japanese import cars (Grey Imports) to receive UK radio transmissions. It achieves this by shifting the UK transmission FM frequencies into the band that the Japanese radio will detect. For example, shifting a UK radio station that transmits at 100MHz by 16 MHz will allow the station to be received by the Japanese Radio at 84MHz.

Japanese radios have a bandwidth of 14MHz (76-90MHz) compared to the UK bandwidth of 20MHz (88-108MHz), hence a certain band of frequencies will be lost in the shifting process. For flexibility there are three variations in the Band Expander range.
